Iji Ala — sacred geodesy

- Iji Ala/Iji Ana — the "meta-science" of bringing celestial harmony to earth (Anakwudo-ma-Enukwudo); credited with feats like the geothermal pyramid settlements (Nsude pyramids, Abaja) via Ikwunite-Aba-Igwe ("raising the crown of the celestial mound").

- Houses and environs can be ensouled (and un-ensouled after occupants' death); the ritual technocrat-kings: Eze Akum, Eze Okpoko, Eze Ana, Eze Mkpume, Eze Uzu, Eze Oba — masters of stone, metal and element (the Umu Mkpume of Oba; Uzu Akoli's stone: okwute hiri ehi... o zi mbunata).

- Shrines/groves reframed as "places of pure spiritual energy" for revitalizing devotion (Isa Ajasinobi), realigning mind (Ichikota-Uche-na-Mmuo), replenishing soul-force (Idu-Ikenga-Chi). (Modern application argument by Nwafor.)
